The Doe Run Co. is an international lead producer with recycled and primary lead producer operations. Doe Run’s Viburnum facility, which is a mining site that began in 1959, is located on Casteel Drive in Viburnum. Since the mid-1990s, Doe Run used the leaded cathode ray tube (CRT) glass, also known as silica, as flux for blast furnaces in both primary and secondary smelter operations. Doe Run recycled the CRT glass, mostly from old computer monitors, at the Central Services Operation of The Doe Run Co.-Buick Resource Recovery Facility, located at the Viburnum Facility. The facility included four storage areas.
In 2005, Doe Run began negotiations with the department in an effort to appropriately regulate the activity at the CRT facility. During these discussions, the Environmental Protection Agency (EPA) promulgated a final rule in July 2006, conditionally exempting used CRTs and gall from CRTs from the definition of a Solid Waste under the federal Resource Conservation and Recovery Act (RCRA), effective January 29, 2007.
On May 23, 2007, the department, Attorney General's Office and Doe Run entered into a Settlement Agreement that provided for management of the CRT facility operations and required investigation and remediation of lead concentrations exceeding background levels where CRT glass material was managed. Initial investigations confirmed high lead concentrations in the soil in five areas at the facility. The soil was removed and areas capped with clean soil. In 2010, Doe Run filed, with the Iron County Recorder of Deeds, an Environmental Covenant in the chain-of-title for the affected property, which will notify in perpetuity, any potential purchaser of the environmental conditions of the property. The Environmental Covenant restricts the property to non-residential land use, prohibits disturbance of the soil and requires inspection and maintenance of the soil cap. The Settlement Agreement was terminated in January 2011.
As of 2013, there are no additional requirements under the Missouri Hazardous Waste Management Law for this facility.
